How to put the ignition switch:

Step 1: Take out the malfunctioning ignition switch:

Whether the switch is mounted on the dash or the steering column, you must remove the trim to access it. After disconnecting the ignition switch‘s electrical connections with the proper tools, loosen and take out any screws holding the switch in place. Remove the old ignition switch from its place with caution.

Step 2: Install the new part in step two:

Replacing the ignition switch usually entails reattaching any removed covers or panels, securing it in place, and connecting the new ignition switch to the electrical wiring harness. But you must make sure that there are no parts to swap out.

Step 3: Check how it functions:

Give the new ignition switch a test before putting everything back together. Turn the key to the ON position first, then to the START position, and reconnect the vehicle’s battery. Make sure no problems are starting the engine. Certain cars require programming of the immobilizer system, which you will have to hire out to a locksmith or dealership service facility to finish.


Reassemble the steering column cover and any other parts you removed after the ignition switch’s proper operation has been verified. Verify every screw and connection twice to ensure a secure fit.


Even though changing an ignition switch is usually simple, there could be difficulties involved. Common problems include electrical malfunctions, trouble turning the key, and intermittent starting issues. If you run into any issues:

  • Make sure every connection is tight and correctly crimped.
  •   Examine any broken cables or connectors and replace them as necessary.
  •   Make sure the replacement ignition switch fits the make and model of your car.
  •   Look for security codes that suggest you need to program your car.
  •   If problems still arise, refer to your car’s handbook or get expert advice from a reputable mechanic.

How do you install an ignition switch?

Pinch the release pin on the ignition switch. So it’s flush with the side easily. Now press the release pin that stopped the old switch from coming out. Then, slide the switch into place inside the ignition module. Install it at the same angle and orientation as your old cylinder was installed.

What is the process by which ignition wiring operates? 

The Energy Transfer Process of Spark Ignition Wires. The spark from the distributor or ignition coil is transferred to the plugs by spark plug wires, also known as ignition wiring. Your engine’s combustion chamber’s air-fuel mixture is ignited by the next spark.

Which wires are connected to the ignition switch? 

The yellow or red wire is called the ignition input wire (IGN) and it signals the ignition system of your car to turn on. Without it, you could end up with a non-starting car and stranded on the side of the road.

What supplies the ignition switch with its power? 

Champion Tech Tips: The Operation of Ignition Systems

Primary (battery) current flows from the battery through the ignition switch and onto the coil primary windings when the ignition switch is turned on. The armature rotates past the pickup coil or sensor, turning on and off the primary current.
